Spring preload

Setting

The spring preload on the front
wheel must be adapted to the
weight of the rider. Higher
weight requires a higher spring
preload, lower weight requires a
lower spring preload.
It is essential to set the spring
preload to suit the load carried by
the motorcycle. Increase spring
preload when the vehicle is heav-
ily loaded and reduce spring
preload accordingly when the
vehicle is lightly loaded.
